To all whom t may concern.' I

Be yit known thatI, HANS P. MoLanDER, a resldmg at Ocean Parlgin the county of,` os Angeles,

l, lState of California, have nventedy ,a new and useful Clutch, ofvhichthe following is he inventionrelates to power transmission systems and articularly. toclutche`s.

The princi pal o jectof the invention is to *ovide a clutch which will transmita rol.. pl lshown in dotted lines 1n F 1g. 2 and the tion vofrotation and which will be readily tary movement about ashaft mene direcreleased upon a reversal of this motion.

A further object of the invention is to provide such a clutch in which the Apower used to reverse ifs-very small and in`wh1ch the area ofthe power transmitting parts subjected to friction will be very large.

Other objects and advantages will be ev1- dent hereinafter.-`

Referring to the drawings which arefor illustrative purposes only: Figure 1 is a side elevation of the invention, some of the parts any, 'sort of machinery, not shown.

being broken away and shown in section to better illustrate the internal construction. Fig. 2 is a section on the plane 2--w2 of Fig. 1, looking in the direction ofthe arrows.

In the embodiment ofthe invention shown in the drawings, a clutch wheel 1 is mounted rigidly on a shaft 2 which is connectedo Ae clutch wheel 1 lis provided with a flange 3 and two clutch shoes 4 bear on the periphery thereof. rlhe shoes 4 are pivoted on pins 5 rigidly secured in outer arms 6 .which are in turn ivoted on pins 7 carried on inner arms 8. "l". earms 8 are pivoted. on pins 9 which are secured on a disk 10 connected by a hub 11 to a driving pulley 12 which turns loosely on the shaft 2 being kept in alinement by a collar 13. Resti-:lining pins 14 are also secured in the disk 10 and the pulley 12, and stop pins 15 are secured in the pulley 12. rllension springs 16 are secured between the outer arms 6 and the pulley 12.

The method of operation of this partielllar embodiment of my invention is as follows: lVhen the pulley 12 is driven by 'a belt or any other convenient means, notshown, in the direction ofthe arrow shown in Fig. 2 the pills 9 are' rotated in a clockwise direc` tionI and the arms 6 and 8 are thrown into the position shoun in full lines in. Fig. 2, the shoes l being held against the clutch l wheel only wheel .l by the springs 16. `When the arms 8 strike the restraining pins 14ey a further straightening of the arms -6 and 8 is prevented and the shoes lare lpressed firmly down against the wheel 1 rotating it in the direction of the arrow. So long as the pulley 12 is rotated in this direction the wheel 4 is'carried around thereby, andthe wheel and pulley turn together. When, however,

the direction of. rotation of the pulley l2 is reversed ther arms 6 and-8 take the position wheel on'said shaft, adriving pulley on said shaft, clutch shoes bearing on the periphery of said wheel, a disk formed integral with said pulley, pivot pins carried` between said disk and said pulley, inner .arms on said pivot pins, outer arms pivoted t'o Asaid inner arms, lmeans for connecting the arms and the shoes, and means for restraining the movement of said outerand inner arms to increase the pressure of said shoes on said when the pulley is turned in one direction.` f i 2. A clutch comprising a shaft, a clutch .wheel on said shaft, a driving pulley on said shaft, clutch shoes bearing on the'periphery of said wheel, a disk formed integral with said pulley, pivot pins carried between said disk and said pulley,.inner arms on saidpivot pins, outer arms pivoted to said inner arms, means for connecting the arms and the shoes, restraining pins fixed in said disk and pulley to preventthe said arms from assuming a straight line as the pulley is turned in one direction.

8. A clutch comprising a shaft, a clutch wheel on said shaft, a driving pulley on said shaft, clutch shoes bea-ring on the periphery of said wheel, a disk formed integral with said pulley, ,pivot pins carried between said disk and said pulley, inner arms on said ivot ins outer arms ivoted to said inner said slices is accomplished when the pulley turns in the opposite direction.

A. A clutch comprising a shaft, a clutch wheel on said shaft, a driving pulley on said shaft, clutch shoes bearing on the periphery of said Wheel, a disk formed integral Awith said pulley, pivoted pins carried between said disk and said pulley, inner arms on said pivot pins, 'outer armspivoted to said inner arms, means for connecting the arms and the slices, springs tending toincrease the pressure of said shoes on said Wheel, and means for restraining the movement of said outer and inner arms to increase the pressure of saidshoes on said Wheel only when the pulley is turned in one direction.A l 5. A clutch comprising a shaft, a clutch wheel on said shaft, a driving pulley on said shaft, clutch shoes bearing on the periphery.- of said wheel, a disk formedlintegral with said pulley, pivot pins carried between said disk and said pulley, inner arms on said.

pivot pins, outer arms pivoted to said inner arms, means -for connecting the arms and the shoes, springs tending to increase the pressure of saidv slices on said Wheel, restraining pins fixed in said disk and pulley to prevent the said arms from assuming a stralght line as the pulley is turned in one direction.

G. A clutch comprising a shaft, a clutch Wheel 011 said Shaft, a driving pulley on said shaft, clutch shoes bearing on the periphery ofsaid wheel, a disk formed integral with said pulley, pivot pins carried between said disk and said pulley, inner arms on said pivot pins, outer arms pivoted to said inner arms, means for connecting the arms and the shoes, springs tending to increase the pressure of said shoes on said wheel, and means for restraininglthemovement of said outer and inner arms toincrease the pressure of said shoes on said iheel only when the pulley is turned in one direction and whereby a quick release of said shoes is ac'con-iplished when the pulley turns in the opposite direction.

, In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 29th day of July, 191%.
